To all 'whom it mdp/concern: Be` it known that '1,' Jonav HAHN, a citizen ofthe United States, residing at Los Angeles, in the countyr of Los vAngeles and lState of California. have invented a new. and useful Rump-Fitting, of which the following is la specification'. y

This inventionrelate's to a device adapted' tohe appliejdlat-.the'ftop yoif-a deep well to,

facilitate 'the `ipnstallz'ltion, "operation -and adaptedv for use in {in st'allin'g,` operating, removing andv replacing `"c'asing,""'pump tubing and sucker' rods iand from wells.

A. further object is to 'provide anap'pliance, whichf'will prevent the'l liability of dropping the sucker-rod `olv-tubing into the'4 well during the proce of lowering and elevatingthe same and' to provide a. wrench to hold themsucker-rodand the .tubing from.

The tubing-head or coupling l is provided g0n;diametrically opposite sides ,with pivots 2 and on'ot-her diametrie'ally opposite sides' 'midway between the pivots 2 with orifices '3 formed in a projectingrimtpreferablyinf tex-nally beveled and is also provided inter- Anally with a screw-threaded socket 5 at the lower end and a screw-threaded socket 6 at the upper end and with lan inwardly projecting shoulder 7 between the sockets 5 and. rG. The pivots 2 are adapted to receive an elevator bail 8 by which the conpling-head 41 may` behandled inlowering, elevating,

screwing and unscrewing it. The orifices 3 are adapted to receive and loosely fulerum .detachable levers of tht: first-class comprisingahandles 9.of any desired shape and comc1-amp jaw shownfin Figs.. n-eand 3, which catcher shownin prising tapered, wedge-shaped clamping jaws 10. The loweriscrew-threaded socket 5 is adapted to" screw onto the tubing 11 and the -upper screw-threaded socket 6 is adapted to seatv the pump head 12;

Two forms oi clamping jaws are shown in the drawings. The form 10,being adapted and which' rod is provided .at its upper end with a head 14 in which the ribs terminate.

Said jaws 10 are provided with tapered for supporting theribbed sucker rodjl3, described in my said vformer application,

said recesses are insufficient, to allow4 the head 14 topass the jaw so that when a pair of the jaws 10'is in placein the couplinghead, their Vhandles being inserted throughv vthe orifices 3, the jaws, when closed,l will A v 'allow the sucker rod 13 to s lide freely np and down and vwill notfallow the h ead 14 to pass-- downward v'past the jaws. .The handles 9 are bent and 'affordfa pivot-space` '17'between Athe topy ofthe handle and -the top of the Vjaw' toaccommodatethebars 4 f formed -jby rini ltand are perforated to receive pins. 18 so ltl'mt-saif-l jaws may be de-v tachably secured inthe orifices 3, and may tion,1andiricegversa ,-an l. when they are' in for the j'aws;"sai jaws serving-to. prevent" orm'- suplbe notched so as'to-iillowthefnothes to engage the rim 4: to sustain: thej aws in their 'up-tilted or retracted. positionyshown in dotted lines in: Figi; 3, thus :leaving the space -aboye the screw-threaded'soket 6 freev4 to allow the downward vpassage of the joints betweenthe` sucker rod sect-ions. A' j By reeren'ce'to Fig. 2 it will beseen that the coupling-head 1 is adapted to-servejasan elevator forth'e suckerrod lltwhen the jaws are closed on the Iribbed body of the sucker rod, provided the.. coupling head is unscrewedfrom the tubing; and that; the

The up er screw-threaded socket of the coupling ead adaptsthe coupling-head for the reception of the pump head 12, and said pump head is `provided with'a laterally pro jecting spout 21, and above said spout with a packing chamber 22 which tapers 'flownward at its lower end and is'provided at its jupper end with'ascrewfthreaded seat 23y for the'packing gland-324; #Inside thefsaid 4chamber 22 is providedl a jresilient packingl sleeve 25 which is` tapered from the middle toward both ends and is ireversely slitted 70. from its ends; the slits'26'from one end extending beyond the slits 27 from the other pressed toward its axis.
